Portland, Maine sits roughly 180 km north of Boston, and the journey is one of the few intercity train routes in New England where Amtrak's Downeaster genuinely holds its own against the bus and the car. Whether you want a relaxed ride through coastal Massachusetts and New Hampshire or the cheapest fare you can find, here is how the options compare.
The most comfortable way: Amtrak Downeaster
The Amtrak Downeaster is the dedicated intercity train linking Boston North Station to Portland, with stops at Woburn, Haverhill, Exeter, Durham and Dover along the way. The journey from Boston to Portland takes roughly 2 hours to 2 hours 30 minutes, depending on the service and any minor delays on this single-track line.
Trains run several times a day in each direction, including an early-morning departure and an evening return that work well for a day trip. The Downeaster is comfortable, scenic and delivers you to Portland's Thompson's Point station — just a short ride from the Old Port and the city centre. Reservations are required and advance booking typically secures lower fares. The Downeaster is one of the more reliable intercity services in the US Northeast. See our guide to travelling the USA by train for broader context on the Amtrak network.
The cheapest way: Concord Coach Lines
Concord Coach Lines is the main scheduled bus operator on this route, running several times daily from South Station in Boston (with additional pick-up at Logan Airport) to Portland's Transportation Center. Journey time is roughly 2 hours to 2 hours 30 minutes in good traffic — comparable to the train but more variable, as the I-95/Route 1 corridor north of Boston can back up significantly during peak periods.
Fares on Concord Coach are generally among the lowest on the route, and the service has a good reputation for comfort and punctuality relative to the competition. The buses are clean and air-conditioned, with on-board Wi-Fi on most services. The Logan Airport stop makes Concord Coach particularly convenient if you are arriving by air and heading straight to Maine.
Other bus options
Greyhound also serves the Boston–Portland corridor, often at competitive fares. FlixBus has expanded in New England and may offer services on this route depending on the season. As with any budget coach, check the pick-up and drop-off points carefully — some services use stops further from central Portland than others.
Driving the route
The drive from Boston to Portland covers roughly 180 km and typically takes 1 hour 45 minutes to 2 hours in light traffic — but "light traffic" in this corridor is relative. The stretch of I-95 through greater Boston and into Massachusetts can be brutal on Friday afternoons and summer weekends, when coastal Maine is a popular destination and everyone seems to leave at once. Budget two and a half to three hours if you are travelling at peak times.
Driving makes sense if you plan to explore Maine beyond Portland — the coastline north of the city, Acadia National Park, and the Lakes Region are all far more accessible by car than by public transport. If Portland itself is your only destination, the train or bus spares you the parking challenge in a city where central parking can be expensive and limited.
Getting around Portland on arrival
Portland is a compact, walkable city for most of its most popular areas. The Old Port, Congress Street, the waterfront and most hotel clusters are all reachable on foot from either the train station or the bus terminal, or with a short taxi or rideshare. A hire car is worth considering if your onward plans take you further into Maine.
Booking tips and fares
Amtrak's Downeaster fares typically rise as a departure fills, so booking a few days to a couple of weeks ahead — especially for weekend and summer travel — tends to secure a noticeably better price than buying on the day. Amtrak also offers occasional rail passes and multi-ride options that can be worth investigating if you plan to travel this corridor more than once. Concord Coach fares are generally more stable day to day, and walk-up tickets are usually available outside the busiest holiday weekends, though booking ahead online still guarantees a seat on your preferred departure.
Luggage and onboard comfort
The Downeaster has generous overhead and end-of-car luggage space, at-seat power outlets, a café car serving snacks and drinks, and free Wi-Fi — a genuinely comfortable way to cover the distance, especially compared with sitting in traffic. Concord Coach buses are similarly well equipped with reclining seats, onboard Wi-Fi and underfloor luggage holds for larger bags, making either option a reasonable choice if you are travelling with more than a carry-on.
Seasonal and weather notes
New England winters can bring snow and ice that slow driving significantly and occasionally cause minor delays on the rail line, though the Downeaster is generally reliable year-round. Summer and early autumn are the busiest travel periods, as visitors head to the Maine coast for beaches and foliage respectively — booking ahead for both train and bus during these peak weekends is sensible. Foliage season (roughly late September into October) is a particularly scenic time to take the train, with the New Hampshire seacoast and southern Maine woodlands in full colour.
Common mistakes to avoid
The most consequential mix-up, as already flagged, is confusing Portland, Maine with Portland, Oregon when booking any onward travel or accommodation — always double-check the state before finalising plans. Another frequent oversight is underestimating I-95 traffic on summer Fridays; travellers who assume the drive will take under two hours can find themselves stuck for considerably longer, making the train's fixed schedule the more dependable choice on exactly those peak-demand days.
Which should you choose?
The Amtrak Downeaster is the most comfortable and scenically pleasant option — particularly for the run along the New Hampshire seacoast — and its travel time is competitive. Concord Coach is the best bus option, with reliable service and a useful Logan Airport stop. Driving comes into its own if you plan to explore the Maine coast beyond Portland, but avoid it on summer Fridays. For a different New England day trip from Boston, see Boston to Cape Cod.
